Problem 92IP

Referring to Example 7-8 Suppose the car has a mass of 1400 kg and delivers 48 hp to the wheels. (a) How long does it take for the car to increase its speed from 15 m/s to 25 m/s? (b) Would the time required to increase the speed from 5.0 m/s to 15 m/s be greater than, less than, or equal to the time found in part (a)? (c) Determine the time required to accelerate from 5.0 m/s to 15 m/s.

Solution 92IP

Step 1 of 4

From the data given, we are required to calculate the time when the car increases its speed from an initial to a final value.
